Acoustic Revive USB-1.0SP and USB-1.0PL cable

Acoustic Revive of Japan suggests that problems of conventional USB cable for audio use is that the signal line and power supply line are installed together in parallel and radiation noise can affect sound quality.  

Wireworld tried to separate the power supply line using dielectric shield in their Starlight range, but Acoustic Revive has gone a step further - separate the two completely.

USB-1.0SP and USB-1.0PL are equipped with two independent cables consisting of a two-core shielding structure with a 100% shielding effect obtained by using a copper foil.

USB-1.0SP employs two A-Plugs for the output side to achieve perfect separation of the signal line and power supply line.  (Imagine a two-headed snake!)  A PC is normally equipped with several USB outlets conveying the same signals, therefore, you can bring out the signal and power lines separately from the output, AR is claiming a dramatic improvement in sound quality, channel separation and S/N ratio.

Neo d+ USB cables

Came across this new series by Oyaide.  Looks interesting.  Price range around $40-$120.
From the website:


The world of PC audio is rapidly expanding as the next-gen listening style. “d+ USB” which is originally designed for sound professionals also functions as the core of the digital data transmission of the PC audio. Due to the fact that there are no change of the frequency balance by cable in the data transmission, “d+ USB” delivers the clean and stable data for an USB-DAC.
The most important factor for digital is lossless, speedy and accurate data transmission. And a cable has many factors which affect sound quality and cause the errors of data transmission such as noise by electro-magnetic wave, impedance matching, and attenuation of electric signal. 
Based on the basic concept of the data transmission, we put noise protection and excellent electric characteristic to the cable into practice applying our long-time experience of the cable production. “d+ USB ” was produced as a result of considering the best combination of structure, conductor, diameter, insulator, shielding, sheath and even the contact pin of the connector. 
Furthermore, we especially considered the industrial design to provide the stylish appearance on your desktop.
